How Yandex.Metrica detects the traffic source
Incoming traffic sources are detected via the referrer (the HTTP Referer header) and tags. If you need to replace the referrer with your own, use the utm_referrer parameter.
Yandex.Metrica uses a tag to detect traffic sources if the tag is included in the data for the first pageview during a user session. If there isn't a tag in the first pageview, the traffic source is detected from the referrer.
For example, a user clicked through to the site from a browser bookmark (the first pageview). Then the user left the site, but came back within 30 minutes by clicking a link with a tag in an email (the second pageview during the session). This session would be considered direct traffic to the site.
